摘　　要：本文提出了大震裂度下多层剪切型结构基于首次超越和累积损伤双重破坏准则的抗震可靠性的计算方法。文中,在导出了多层剪切型滞后结构,在大震烈度下相对层位移最大延性反应的概率分布函数和层滞后吸收能量的概率密度函数的基础上,得到了建筑结构基于双重破坏准则抗震可靠性的计算公式。据此计算的工程实例的结果表明,本文方法具有较好的精度。This paper presents a method for calculating reliability of multi- storey shear structures underearthquake excitation with large shake intensity based on the double damage criterion, that is the firsttime overstep failure and the cumulative damage. In the paper,the calculating formulas of earthquakeresistant reliability based on this criterion for building structures are obtained by deriving theprobability distribution function for maximum ductility responses of relative storey displacement andthe probability density function for absorbed hysteresis energy of storey of the structures underearthquake excitation with large shake intensity. The results of an example calculated by theseformulas indicate that the method has sufficient precision.
